\ RECORDER. 7

To all whom it may concern.

Be'it known that I, WENDELL Hnss, Jr., a citizen of the United States, residin at Tro in the county of Rensselaer and tate of ew York, have invented certain new and useful Improvements in Recorders, of which the following is a specification.

This invention relates to recorders and particularly to a recorder of the continuous type capable of giving a continuous record of long duration and lar e scale on a record sheet of relatively sma size. To accomplish this result the records for a number of successive time LIperiods are super osed on a single sheet, e records for di erent time perlods being distin ishable by their color. The recorder thus involves means for causing the recording mechanism to traverse the record a number of times, one for each time period, and a color chan e mechanism operative to change the reoor color at the beginning of each traverse.

I illustrate the invention as a plied to a water stage recorder capable making a record of water stages through eight successive periods of one week each.

In the drawings Figure 1 is a side elevation of the complete device,-a part of the clock casing being broken away to show arts of the gearing; Fig. 2 is a view simiar to Fig. 1 but showing the cloc case and pencil turret in section; Fig". 3 is a an. view, partly sectional showing the turret and carriage, the clock driven le'ad screws, and the reversing gears for the lead screws; Fig. 4 is a fragmentary elevation showing the reversing gear. trains for the lea screws; Fig. 5 is an enlarged view of the turret showing the turret catch just ready to 'trip off at the moment of reversal; Fig. 6 is a somewhat similar view showing the turret catch. approaching the completion of its tri ofi action; Fig. 7 is a vertical section o the turret; Fig. 8 is a section on the line 8-1-8 of Fig. 7; Fig. 9 is a f mentary elevation showing the alining gui e for the pencil oin'ts; and Fig. ,10 is a perspective view 0 the end of the tippin track and the track catch for controlling t ereversing gears and the turret catch.

The entire mechanism is mounted on a base 11 which carries a supporting frame structure consisting of a bracket 12 and a Specification of Letters Patent.

'The mit t e settin of the recording device with Patented Jan. 9, 1917.

casing 13 which are tied together by a tie rod 14. The casing 13 is for inclosm the clock mechanism and certain'parts o the gearing later to be described. Access to the casing is had by means of a door 16. The record drum 17 which is shown as covered by a suitable record sheet is mounted with its axis horizontal in bearin 18 and 19 m the casing 13, and the bracfizt 12 respectively. The drum 17 is provided with a gear 20 which meshes with a similar gear 21 on a shaft 22. This shaft 22 turns in a sleeve bearing 23 removably mounted in the bracket 12 and carries a P111 sprocket 24 over which runs a perforated bronze tape 25. One end of the tape 25 is connected to a float 26 and the other to a counter-weight of usual form (not shown). The counterweight and float coact in the usual manner to rotate the sprocket 24 in reverse directions as the float 26 rises and falls. In this way the drum 17 is caused to rotate in response to movements of the float. A pair of retaining guides 27 are mounted in a lug 15 on bracket 12, and these confineth'e ta e 25 to the sprocket 24.

ounted in the casing 13 is a clock movement of usual form which is generally indicated by the reference numeral 28 the working parts not being shown in detail. This movement is driven through the pinion 29 which meshes' with the gear 30. The gear 30 is driven by means vof a heavy wei ht on the chain 31 which runs over the sproc et 32. The sprocket 32 and the gear 80 are connected together by means of a pawl and ratchet mechanism 33 to ermit the rewinding of the weight carrie by the chain 31. This art of the mechanism is merely a clockrive. of the weight type, built somewhat more heavily than usual and provided with a weight heavy enough to furnish the necessary ower through a relatively short fall, the c ock being intended to run about ei ht weeks on one windin he center shaft 84 of t o clock, which makes one revolution in sixty minutes, is releasably held by a split clams 35 provided with a clamping screw 36 to a rive gear 37. urpose o releasing the gear is to perreferenceto e clock. The gear 87 meshes with two companion gears 88 and 89 which are journaled on a yoke and the yoke 40 is journaled to swing about the axis of the gear 37 so as to cause the gear 88 to mesh with a gear 42 or to cause the gear 69 to mesh with a gear 41. The gear 42 is an idle gear between gear 41 and a similar gear 43 and constrains them to rotate in a common direction. The shiftin of the yoke 40 thus causes a reversal of too drive of the ars 41 and 43. The parts are so pro ortioned that the gears mesh properly as t e yoke 40 shifts back and forth. The gears 41 and 43 are each fast to a corresponding one of two lead screws 44 and 45 which are mounted in bearings 46in the easing 18 and in companion hearings in the frame 18. o

The yoke 40 carries a pin 47 which is connected b a link 48 to one of the two arms of a bel crank 49. The other arm of the bell crank 49 is connected by a link 50 to a rocking track 51 which is pivoted at its middle on the track 52 carried b the bar 14. This rocking track is para lel when viewed in plan, to the lead screws and 45, and is ca able of a limited tippmgmovement to 6161181 side of its horizontal osition. In its extreme tipped positions it is held alternately by two spring held catches 53. The tipping of the track 51 from one limiting osition to the other shifts the yoke 40 ack and forth so as to reverse the direction of drive of the lead screws as will be apparent from an inspection of iounted on the lead screws 45 and guided and driven thereby is a carriage 54 whose form is best shown in Fi s. 4 to 9. This carriage carries two tri -0 pins 55, which are adjustable and, whic engage the catches '53 alternately to trip the same, and release the tipping track 51. Carriage 54 has a projecting pin 56 which engages a vertical slot in a secondary carriage 57 to cause the secondary carriage to move with the carriage 54, while permitting the relative upward and downward movement of said secondary carriage. This secondar carriage 57 is provided with flanged rol ers 58 running on the tipping track 51. The carria 57 carries a pendent weight 59. Thus as t e carriage 54 moves along the lead screws the carriage 57 moves u the inclined track'51'and when the trip orces backthe corre ending catch 53-the weight 59.carried b t e cama e 57 furnishes the power to s ift the inc ined track 51 to its reverse position. This shifting reverses the direction of rotation of the lead screws and starts the carriage 54 movin back in the reverse direction.

addition to reversin the position of the track the descent of t e seconda ,carria e is caused to release the color an mec anism for a limited movement at t e moment of reversal so as to bring a new encil of a different color into marking re ation with the record drum as will later be described in detail.

The carriage 54 is of the form clearly shown in Fi 7 and carries an inclined plate 61 against w ich the oints of a number of pencils, carried by t e turret, rest. The plate 61 extends downward almost into contact with the record drum, and serves to guide the pencilsinto and out of contact with the record drum when the turret rotates. The carriage 54 carries an upstanding fixed pin 62 and on this is journaled, by means of a sleeve 63, the turret, which comprises a base late 64 and a number of upstanding tubu ar guides65. In the present instance eight of these guides are shown. This turret is urged to rotate in a counter clockwise direction, as viewedin' plan, b a coiled s rin 66. This spring is coi ed around t e s eeve 63 and is connected at one end to a collar 67 fast on the spindle 62, and at the other end to the base late 64. A plurality of catch pins 68 one or each guide extend radially from the base plate 64, and the turret is held from rotation under the action of the spring 66 by means of a hook pawl 69 whic is urged into engagement with successive pins 68 by means of a spring 70. o

Each pencil is held in a clampin sleeve which consists of a split tube 73 sliding in a guide 65. These urge the pencil down by their weight and that pencil which is in marking position is further held by a spring plate 71 carried on an adjustable telescopic standard 7 2. I

The release of the turret catch at each reversal of the carria c has already been mentioned. This is e ected by a spring held 3 catch 74 which is pivoted on the up er end of the secondary carriage 57, and w ich as the carriage 57 rolls up the track 51 slowly overtravels and enga es the rear end of the hook pawl 69. At t e endof thetravel of I the carriage 54, when the tiltin track is released an drops, the descent o the carriage 57 pulls down. the rear end of the pawl 69 through the engagement therewith of the catch 74, but the catch 74 is immediately wiped back b means of a cam or wedging lug 75 forms on a portion of the carriage 54. Thus the pawl 69 is pulled out of engagement and immediately released, so that it returns uickl enough to enga e the next in 68 to t at w ch it releases, t us allowing the turret torotate sufiiciently to bring a new pencil into marking position, but no fartiher. Other suitable escapements may be use A ga plate 76 is pivoted at 77 on carriage 5 and is used to al ine the encils with the cofirdinate lines on the recor sheet as indicatedin Fig. 9.

The operation of the device is as fols onding'mianner. At the same time the' c ock'm'ec'hanism is driving the lead screws in one dil'ection or another so as to feed the carria 54 in one or another cor ending direction. As the carriage moves ong the lead screws the secondary carriage 57 is constrained to move withit lifting its wei ht as it runs up the in ed track 51. At he end of its travel the carriage 6i tri 8 d one of the catches 53 and the sudden esccnt of the carriage fill-under the {action of the weigpt' 59 reverses the inclination of the trac 51 and 'consefluently the direction of rotation of the lea screws. At the same time it momentarily releases the turret so that this may rotate the distance between two successive pencils and present a new pencil at the recording point." These pencils are of difierent colors and the order of their arran ement is fixed accordin to any accepte convention. In themac e as lllll'S- trated the carriage moves the ion h of the record drum in one week. Thus t e records for successive weeks are made in reverse directions; and the record of each successive week is in a characteristic color. Consequently the records ma bereadilydistinguished and interpre even though they are superposed, and it becomes possible to,..

make a record for eight weeks without reduction in scale on the same size record sheet as has heretofore been used for making a similar record for a sin is week.

In the claims I use t 0 term graph or record graph to indicate therecord line which is marked on the record sheet 'or blank. I use the'word pencil as a generic term to include analogous marking means capableof read substitution in the relation ecified, and shall -use'the expression color change mechanism in its broad sense to include any mechanism capable of giving. the color change feature characte stic o thisinvention'." 7
